1. Objective of ExperimentTo understand basic concept of aerodynamic forces, potential flow, and find coefficient of lift and drag from the experiment
2. Basic Theory
2.1. Aerodynamic force
Aerodynamic force is exerted on a body by a gaseous fluid in which the body is immersed due to their relative motion. One of the most common
examples of aerodynamic force is airplane.
Drag : The air resists the motion of the aircraft and the resistance force is called drag. The direction of drag force opposes thrust force. Like lift, there are many factors that affect the magnitude of the drag force including the shape of the aircraft, the "stickiness" of the air, and the velocity of the aircraft. Like lift, we collect all of the individual components' drags and combine them into a single aircraft drag magnitude. And like lift, drag acts through the aircraft center of pressure.
Lift : To overcome the weight force, airplanes generate an opposing force called lift. Lift is generated by the motion of the airplane through the air and is an aerodynamic force.
